This. I bought a Domane when they still had men's and women's version (now I think the Silque has replaced the WSD version of the Domane). I was fitted as needing a 56 cm. The bike guy and I went over the differences in geometry between the men's and women's version (at least at the 56 cm, he said it might have been different in the smaller sizes) were:

(1) Color. I liked the men's color anyway;
(2) Delivery Date. I ordered in July and received the men's version in September. I was told that the delivery dates for the women's versions were unknown, estimated sometime the next spring (it was a new model launch and I think they simply didn't know about demand); and
(3) Different saddles. It was worth buying a new saddle to get my new and exciting bike a lot earlier.

Lately I've been looking at the Ruby/Rubaix and in the larger sizes there were differences, but not significant (besides I think the Rubaix is available in 54cm and 56 cm, whereas the Ruby goes from 54 cm to 57 cm). I haven't pulled the trigger on that yet though :-)
